Looking at Nothing: Investigating The Lights from a Black Hole

Being one of the most advanced theories of its time, (and its past) general theory of relativity (GTR) was viewed as a fundamental necessity to account for the discrepancies in Newtonian gravity. Trying to account for the changing precession of Mercury, Einstein’s theory ended up unleashing hidden (quite literally) monsters in the extreme gravity. Black holes being probably the most famous example of that. This year, the Royal Swedish Academy of Sciences decided to award the Nobel Prize to two milestones, for the proof of the theory of the very existence of the black hole and ingenious methods to observe them.
